EATON VANCE TAX-MANAGED DIVIDEND INCOME FUND as of April 30, 2004

LETTER TO SHAREHOLDERS

[PHOTO OF THOMAS E. FAUST JR.]
Thomas E. Faust Jr.
President

We are pleased to welcome shareholders of Eaton Vance Tax-Managed Dividend
Income Fund (the "Fund"), the first equity income fund designed to take
advantage of new favorable tax rates on dividend income. The Fund's investment
objective is to achieve after-tax total return for its shareholders. The Fund
invests primarily in a diversified portfolio of common and preferred stocks that
pay dividends that qualify for federal income taxation at long-term capital
gains rates.

For the period from inception on May 30, 2003, through April 30, 2004, the
Fund's Class A shares had a return of 9.44%. That return was the result of an
increase in net asset value (NAV) per share from $10.00 on May 30, 2003, to
$10.64 on April 30, 2004, and a distribution of $0.297 per share in dividend
income.(1) The Fund's Class B shares had a return of 8.79% for the same period,
the result of an increase in NAV per share from $10.00 to $10.63, and a
distribution of $0.243 per share in dividend income.(1) The Fund's Class C
shares had a return of 8.79% for the same period, the result of an increase in
NAV per share from $10.00 to $10.63, and a distribution of $0.243 per share in
dividend income.(1) (SEE PAGE 5 FOR MORE PERFORMANCE INFORMATION.)

WITH TODAY'S LOWER TAX RATES, IT IS STILL IMPORTANT FOR INVESTORS TO CONSIDER
TAX EFFECTS...

A year ago, Congress passed legislation that included several provisions that
affect individual investors. The most important aspects of the Jobs and Growth
Tax Relief Reconciliation Act of 2003 for individuals are a lowering of tax
rates for ordinary income and long-term capital gains and a change in the tax
treatment of qualifying dividend income, which is now taxed at the same rates as
long-term capital gains, rather than as ordinary income.

The biggest change for equity investors is that qualifying dividend income is
now taxed at much lower rates than other investment income and short-term gains
(maximum rate of 15% vs. 35%). The spread between short-term and long-term
capital gains tax rates has also increased. These changes increase the
importance of achieving a mix of returns that emphasizes long-term gains and
qualifying dividends over less favorably taxed short-term gains and
non-qualifying dividends and other investment income. Deferring taxes on
long-term gains continues to be of significant value, particularly for investors
with longer time horizons and for assets earmarked for inheritance.

Taxes continue to be the single largest cost borne by long-term equity
investors. Strategies to help minimize tax effects can add real value to taxable
accounts. Just as before, it makes sense for taxpayers to invest in funds that
share their objective of after-tax returns.


                                             Sincerely,

                                             /s/ Thomas E. Faust Jr.

                                             Thomas E. Faust Jr.
                                             President
                                             June 4, 2004


(1)  Returns do not include the 5.75% maximum sales charge for the Fund's Class
     A shares or the applicable contingent deferred sales charges (CDSC) for
     Class B and Class C shares. If the sales charge was deducted, the
     performance would be reduced.

     Past performance is no guarantee of future results. Returns are historical
     and are calculated by determining the percentage change in net asset value
     with all distributions reinvested. Investment return and principal value
     will fluctuate so that shares, when redeemed, may be worth more or less
     than their original cost. Performance is for the stated time period only;
     due to market volatility, the Fund's current performance may be lower or
     higher than the quoted return. For the Fund's performance as of the most
     recent month-end, please refer to www.eatonvance.com.

  MUTUAL FUND SHARES ARE NOT INSURED BY THE FDIC AND ARE NOT DEPOSITS OR OTHER
OBLIGATIONS OF, OR GUARANTEED BY, ANY DEPOSITORY INSTITUTION. SHARES ARE SUBJECT
       TO INVESTMENT RISKS, INCLUDING POSSIBLE LOSS OF PRINCIPAL INVESTED.

EATON VANCE TAX-MANAGED DIVIDEND INCOME FUND as of April 30, 2004

MANAGEMENT DISCUSSION

AN INTERVIEW WITH MICHAEL R. MACH AND JUDITH A. SARYAN, PORTFOLIO MANAGERS OF
EATON VANCE TAX-MANAGED DIVIDEND INCOME FUND

[PHOTO OF MICHAEL R. MACH]
Michael R. Mach, CFA
Portfolio Manager

Q: MICHAEL, CAN YOU GIVE US AN OVERVIEW OF HOW THE STOCK MARKETS PERFORMED IN
   THE PERIOD SINCE THE FUND COMMENCED BUSINESS?

A: MR. MACH: The overall markets delivered healthy returns during the 11-month
   period ending April 30, 2004. This performance was driven by an improving
   economy, robust corporate earnings, and historically low interest rates. The
   markets also saw an increase in volatility, as geopolitical tensions kept
   investors apprehensive.

Q: HOW DID THE FUND PERFORM IN THIS ENVIRONMENT?

A: MR. MACH: Eaton Vance Tax-Managed Dividend Income Fund benefited from the
   strong performance of both the domestic and international markets. During the
   11-month period ended April 30, 2004, all share classes of the Fund recorded
   positive high-single-digit returns. While the Fund provided shareholders with
   a positive total return for fiscal year 2004, its performance trailed that of
   the Russell 1000 Value Index.(1) The primary reason the Fund lagged the
   Russell 1000 Value Index was its focus on owning common and preferred stocks
   that produce attractive levels of tax-favored dividend income (income that
   qualifies for federal income taxation at the long-term capital gains rate).
   Overall, higher yielding common and preferred stocks generally lagged the
   Russell 1000 Value Index over the past 11 months.

Portfolio Manager

Q: JUDY, COULD YOU ELABORATE ON THE PERFORMANCE OF HIGHER-YIELDING STOCKS?

A: MS. SARYAN: Higher-yielding common stocks tended to lag the overall market
   throughout the Fund's fiscal year. The month of April 2004 was particularly
   punishing for higher-yielding stocks, as higher-than-anticipated job growth
   and strong retail sales figures released by the government caused interest
   rates to jump and triggered investor anxiety about possible future rate
   increases. Fears of rising interest rates caused traditionally interest-rate
   sensitive sectors, such as Real Estate Investment Trusts (REITs) and
   utilities, to pull back and sharply underperform the broader market during
   April. We continue to be positive on the underlying fundamentals of the
   utility, telecommunication services, and REIT shares held by the Fund. As of
   April 30, 2004, the Fund had 44% of total net assets invested in the
   above-mentioned higher-yielding common stock sectors, and of that, 23.0% was
   invested in utilities, 13.3% was invested in telecommunication stocks, and
   7.7% was invested in REITs.(2)

Q: MICHAEL, WHAT OTHER TYPES OF DIVIDEND-PAYING STOCKS DID THE FUND HOLD, AND
   HOW DID THEY IMPACT FUND PERFORMANCE?

A: MR. MACH: In addition to the higher-yielding stocks Judy spoke about, the
   Fund invested in a broadly diversified basket of dividend-paying common
   stocks, including consumer, financial, and industrial stocks. Within this
   sector, the Fund benefited from relatively strong stock selection and from
   being globally diversified. Consumer stocks held by the Fund

   generally benefited from tax rebates, strong new job creation, continued
   mortgage refinancing activity, and improving consumer sentiment. Growing
   demand, coupled with continued global unrest, kept oil and gas prices high
   and generally benefited the energy stocks held by the Fund. As strong
   corporate earnings and free cash flow generation began to fuel a rebound in
   business spending, this generally benefited the industrial stocks held by the
   Fund during the period.

Q: DID THE FUND HOLD ANY FOREIGN STOCKS DURING THE PERIOD?

A: MS. SARYAN: Yes. The Fund's commitment to foreign common stocks also
   contributed to its performance. The strength of the Euro, relative to the
   U.S. dollar, had a positive effect on the Fund's foreign holdings. As a
   result of the weak U.S. dollar, earnings and dividends generated by the
   Fund's non-U.S. holdings got a boost when they were converted back into
   dollars. This provided a favorable tailwind for the Fund's non-U.S.
   investments. As of April 30, 2004, within the Fund's common stock holdings,
   approximately 25.6% of its total net assets were invested in non-U.S. common
   stocks traded on non-U.S. exchanges.(1)

Q: ABOUT 18% OF THE FUND'S ASSETS WERE INVESTED IN PREFERRED STOCKS AS OF APRIL
   30, 2004.(1) WHAT CAN YOU TELL US ABOUT THEIR PERFORMANCE?

A: MS. SARYAN: While the common stock segment of the Fund dramatically lagged
   the Russell 1000 Value Index, the Fund's preferred stock holdings modestly
   outperformed the Merrill Lynch Preferred Index during the Fund's past fiscal
   year.(2) The outperformance of the preferred holdings versus the Merrill
   Lynch Preferred Index was primarily due to the Fund's focus on owning
   preferred stocks that offered qualified, versus non-qualified, dividend
   income, and from owning preferred stocks that generally paid higher coupons,
   while exhibiting less interest rate sensitivity.

Q: DID ALL OF THE FUND'S HOLDINGS PAY A DIVIDEND DURING THE PERIOD?

A: MR. MACH: Yes. At the end of its fiscal year, 100 percent of the stocks held
   in the Fund had paid dividends. In fact, of the 127 common stocks held in the
   Fund at fiscal year end, 95 of them had increased their dividend at least
   once during the period since the Fund commenced operations.(1)

Q: DO YOU HAVE ANY CLOSING REMARKS FOR THE FUND'S SHAREHOLDERS?

A: MR. MACH: For taxable investors, recent tax law changes effectively increase
   the after-tax returns provided by qualifying stock dividends. Given this more
   favorable tax treatment of stock dividends, we found it surprising that over
   the last 11 months, dividend-paying stocks actually underperformed the
   broader markets.

   The Fund continues to focus on investing in companies with attractive
   valuations, strong business franchises, solid long-term earnings prospects,
   and strong cash flow generation capable of supporting future dividend growth.
   We would like to thank you, our shareholders, for your continued
   participation and confidence in the Fund.

   ARE CURRENT ONLY THROUGH THE END OF THE PERIOD OF THE REPORT AS STATED ON THE
   COVER. THESE VIEWS ARE SUBJECT TO CHANGE AT ANY TIME BASED UPON OR OTHER
   CONDITIONS, AND EATON VANCE DISCLAIMS ANY RESPONSIBILITY TO UPDATE SUCH

   change in net asset value with all distributions reinvested. SEC return for
   Class A reflects the maximum 5.75% sales charge. SEC return for Class B
   reflects applicable CDSC based on the following schedule: 5% - 1st and 2nd
   years; 4% - 3rd year; 3% - 4th year; 2% - 5th year; 1% - 6th year. SEC return
   for Class C reflects 1% CDSC.
   Past performance is no guarantee of future results. Returns are historical
   and are calculated by determining the percentage change in net asset value
   with all distributions reinvested. Investment return and principal value will
   fluctuate so that shares, when redeemed, may be worth more or less than their
   original cost. Performance is for stated time period only; due to market
   volatility, current performance may be lower or higher than quoted. For
   performance as of the most recent month-end, please refer to

EATON VANCE TAX-MANAGED DIVIDEND INCOME FUND as of April 30, 2004

NOTES TO FINANCIAL STATEMENTS

1    SIGNIFICANT ACCOUNTING POLICIES

     Eaton Vance Tax-Managed Dividend Income Fund (the Fund) is a diversified
     series of Eaton Vance Mutual Funds Trust (the Trust). The Trust is an
     entity of the type commonly known as a Massachusetts business trust and is
     registered under the Investment Company Act of 1940, as amended, as an
     open-end management investment company. The Fund seeks to achieve after-tax
     total return by investing primarily in a diversified portfolio of common
     and preferred stocks that pay dividends that qualify for federal income
     taxation at long-term capital gains rates ("tax-favored dividends"). The
     Fund offers three classes of shares. Class A shares are generally sold
     subject to a sales charge imposed at time of purchase. Class B and Class C
     shares are sold at net asset value and are subject to a contingent deferred
     sales charge (see Note 6). Class B shares held for eight years will
     automatically convert to Class A shares. Each class represents a pro rata
     interest in the Fund, but votes separately on class-specific matters and
     (as noted below) is subject to different expenses. Realized and unrealized
     gains and losses and net investment income and losses, other than class
     specific expenses, are allocated daily to each class of shares based on the
     relative net assets of each class to the total net assets of the Fund. Each
     class of shares differs in its distribution plan and certain other class
     specific expenses.

     The following is a summary of significant accounting policies consistently
     followed by the Fund in the preparation of its financial statements. The
     policies are in conformity with accounting principles generally accepted in
     the United States of America.

     A INVESTMENT VALUATION -- Securities listed on a U.S. securities exchange
     generally are valued at the last sale price on the day of valuation or, if
     no sales took place on such date, at the mean between the closing bid and
     asked prices therefore on the exchange where such securities are
     principally traded. Equity securities listed on NASDAQ National Market
     System generally are valued at the official NASDAQ closing price. Unlisted
     or listed securities for which closing sales prices or closing quotations
     are not available are valued at the mean between the latest available bid
     and asked prices. Exchange-traded options are valued at the last sale price
     for the day of valuation as quoted on the principal exchange or board of
     trade on which the options are traded or, in the absence of sales on such
     date, at the mean between the latest bid and asked prices therefore.
     Futures positions on securities and currencies generally are valued at
     closing settlement prices. Short-term debt securities with a remaining
     maturity of 60 days or less are valued at amortized cost. If short-term
     debt securities were acquired with a remaining maturity of more than 60
     days, their amortized cost value will be based on their value on the
     sixty-first day prior to maturity. Other fixed income and debt securities,
     including listed securities and securities for which price quotations are
     available, will normally be valued on the basis of valuations furnished by
     a pricing service. The daily valuation of foreign securities generally is
     determined as of the close of trading on the principal exchange on which
     such securities trade. Events occurring after the close of trading on
     foreign exchanges may result in adjustments to the valuation of foreign
     securities to more accurately reflect their fair value as of the close of
     regular trading on the New York Stock Exchange. The Fund may rely on an
     independent fair valuation service in adjusting the valuations of foreign
     securities. Foreign securities and currencies are valued in U.S. dollars,
     based on foreign currency exchange rate quotations supplied by an
     independent quotation service. Investments held by the Fund for which
     valuations or market quotations are unavailable are valued at fair value
     using methods determined in good faith by or at the direction of the
     Trustees considering relevant factors, data and information including the
     market value of freely tradable securities of the same class in the
     principal market on which such securities are normally traded.

     B INCOME -- Dividend income is recorded on the ex-dividend date for
     dividends received in cash and/or securities. However, if the ex-dividend
     date has passed, certain dividends from foreign securities are recorded as
     the Fund is informed of the ex-dividend date. Interest income is recorded
     on the accrual basis.

     C EXPENSES -- The majority of expenses of the Trust are directly
     identifiable to an individual fund. Expenses which are not readily
     identifiable to a specific fund are allocated taking into consideration,
     among other things, the nature and type of expense and the relative size of
     the fund.

     D FEDERAL TAXES -- The Fund's policy is to comply with the provisions of
     the Internal Revenue Code applicable to regulated investment companies and
     to distribute to shareholders each year all of its taxable income,
     including any net realized capital gain on investments. Accordingly, no
     provision for federal income or excise tax is necessary. At April 30, 2004,
     the Fund, for federal income tax purposes, had a capital loss carryover of
     $252,492 which will reduce the taxable income arising from future net
     realized gain in investments, if any, to the extent permitted by the
     Internal Revenue Code and thus will reduce the amount of distributions to
     shareholders which would

                                       15
<Page>

     otherwise be necessary to relieve the Fund of any liability for federal
     income or excise tax. Such capital loss carryover will expire on April 30,
     2012. At April 30, 2004 net capital losses of $873,460 attributable to
     security transactions incurred after October 31, 2003 are treated as
     arising on the first day of the Fund's taxable year ending April 30, 2005.

     For the fiscal year ended April 30, 2004, 67.77% of the Fund's ordinary
     income dividends qualify for the dividends received deduction available to
     corporations and 100% of the ordinary income dividends was qualifying
     dividend income.

     At April 30, 2004, undistributed ordinary income on a tax basis was
     $1,039,396. The difference between book basis and tax basis undistributed
     ordinary income is atributable primarily to differing treatment of certain
     dividends received from the Fund's investment in Real Estate Investment
     Trusts (REITs). The tax character of the dividends paid during the fiscal
     year ended April 30, 2004 was $3,050,110 of ordinary income.

     E FINANCIAL FUTURES CONTRACTS -- Upon entering a financial futures
     contract, the Fund is required to deposit (initial margin) either in cash
     or securities an amount equal to a certain percentage of the purchase price
     indicated in the financial futures contract. Subsequent payments are made
     or received by the Fund (margin maintenance) each day, dependent on the
     daily fluctuations in the value of the underlying security, and are
     recorded for book purposes as unrealized gains or losses by the Fund. The
     Fund's investment in financial futures contracts is designed to hedge
     against anticipated future changes in price of current or anticipated Fund
     positions. Should prices move unexpectedly, the Fund may not achieve the
     anticipated benefits of the financial futures contracts and may realize a
     loss.

     F FOREIGN CURRENCY TRANSLATION -- Investment valuations, other assets, and
     liabilities initially expressed in foreign currencies are converted each
     business day into U.S. dollars based upon current exchange rates. Purchases
     and sales of foreign investment securities and income and expenses are
     converted into U.S. dollars based upon currency exchange rates prevailing
     on the respective dates of such transactions. Recognized gains or losses on
     investment transactions attributable to foreign currency exchange rates are
     recorded for financial statement purposes as net realized gains and losses
     on investments. That portion of unrealized gains and losses on investments
     that results from fluctuations in foreign currency exchange rates is not
     separately disclosed.

     G PUT OPTIONS -- Upon the purchase of a put option by the Fund, the premium
     paid is recorded as an investment, the value of which is marked-to-market
     daily. When a purchased option expires, the Fund will realize a loss in the
     amount of the cost of the option. When the Fund enters into a closing sale
     transaction, the Fund will realize a gain or loss depending on whether the
     sales proceeds from the closing sale transaction are greater or less than
     the cost of the option. When the Fund exercises a put option, settlement is
     made in cash. The risk associated with purchasing options is limited to the
     premium originally paid.

     H SECURITIES SOLD SHORT -- The Fund may sell a security short if it owns at
     least an equal amount of the security sold short or another security
     convertible or exchangeable for an equal amount of the security sold short.
     Such transactions are done in anticipation of a decline in the market price
     of the securities or in order to hedge Fund positions. The Fund will
     generally borrow the security sold in order to make delivery to the buyer.
     Upon executing the transaction, the Fund records the proceeds as deposits
     with brokers in the Statement of Assets and Liabilities and establishes an
     offsetting payable for securities sold short for the securities due on
     settlement. The proceeds are retained by the broker as collateral for the
     short position. The liability is marked-to-market and the Fund is required
     to pay the lending broker any dividend or interest income earned while the
     short position is open. A gain or loss is recorded when the security is
     delivered to the broker. The Fund may recognize a loss on the transaction
     if the market value of the securities sold increases before the securities
     are delivered.

     I USE OF ESTIMATES -- The preparation of the financial statements in
     conformity with accounting principles generally accepted in the United
     States of America requires management to make estimates and assumptions
     that affect the reported amounts of assets and liabilities at the date of
     the financial statements and the reported amounts of income and expense
     during the reporting period. Actual results could differ from those
     estimates.

     J INDEMNIFICATIONS -- Under the Trust's organizational documents, its
     officers and Trustees may be indemnified against certain liabilities and
     expenses arising out of the performance of their duties to the Fund and
     shareholders are indemnified against personal liability for obligations of
     the Trust. Additionally, in the normal course of business, the Fund enters
     into agreements with service providers that may contain indemnification
     clauses. The Fund's maximum exposure under these arrangements is

                                       16
<Page>

     unknown as this would involve future claims that may be made against the
     Fund that have not yet occurred.

     K OTHER -- Investment transactions are accounted for on a trade-date basis.
     Realized gains and losses are computed on the specific identification of
     the securities sold.

2    DISTRIBUTION TO SHAREHOLDERS

     It is the present policy of the Fund to make monthly distributions of all
     or substantially all of its net investment income, if any, and at least one
     distribution annually of all or substantially all of its net realized
     capital gains, if any. Distributions are declared separately for each class
     of shares. Distributions are paid in the form of additional shares of the
     same class of the Fund or, at the election of the shareholder, in cash.
     Shareholders may reinvest all distributions in additional shares of the
     same class of the Fund at the net asset value as of the close of business
     on the ex-dividend date. The Fund distinguishes between distributions on a
     tax basis and a financial reporting basis. Accounting principles generally
     accepted in the United States of America require that only distributions in
     excess of tax basis earnings and profits be reported in the financial
     statements as a return of capital. Permanent differences between book and
     tax accounting relating to distributions are reclassified to paid-in
     capital.

3    SHARES OF BENEFICIAL INTEREST

     The Fund's Declaration of Trust permits the Trustees to issue an unlimited
     number of full and fractional shares of beneficial interest (without par
     value). Transactions in Fund shares were as follows:

4    INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES

     The investment adviser fee is earned by Eaton Vance Management (EVM), as
     compensation for management and investment advisory services rendered to
     the Fund. Under the advisory agreement, EVM receives a monthly advisory fee
     equal to 0.650% annually of average daily net assets of the Fund up to $500
     million, and at reduced rates as daily net assets exceed that level. For
     the period from the start of business, May 30, 2003, to April 30, 2004, the
     advisory fee amounted to $584,010. An administration fee is earned by EVM
     for managing and administering the business affairs of the Fund. Under the
     administration agreement, EVM earns a fee in the amount of 0.15% per annum
     of the average daily net assets of the Fund. For the period from the start
     of business, May 30, 2003, to April 30, 2004, the administration fee
     amounted to $134,771. To enhance the net investment income of the Fund, the
     Administrator was allocated $63,937 of the Fund's operating expenses.

     Except for Trustees of the Fund who are not members of EVM's organization,
     officers and Trustees receive remuneration for their services to the Fund
     out of the investment adviser fee earned by EVM. Trustees of the Fund that
     are not affiliated with EVM may elect to defer receipt of all or a
     percentage of their annual fees in accordance with the terms of the
     Trustees Deferred Compensation Plan. For the period from the start of
     business, May 30, 2003, to April 30, 2004, no significant amounts have been
     deferred.

     EVM serves as the sub-transfer agent of the Fund and receives from the
     transfer agent an aggregate fee based upon the actual expenses incurred by
     EVM in the performance of those activities. For the period from the start
     of business, May 30, 2003, to April 30, 2004, EVM earned approximately
     $6,200 in sub-transfer agent fees.

     Eaton Vance Distributors, Inc. (EVD), a subsidiary of EVM and the Fund's
     principal underwriter, received $320,867 as its portion of the sales charge
     on sales of Class A shares for

                                       17
<Page>

     the period from the start of business, May 30, 2003, to April 30, 2004.

     Certain officers and Trustees of the Fund are officers of the above
     organizations.

5    DISTRIBUTION AND SERVICE PLANS

     The Fund has in effect distribution plans for Class B shares (Class B Plan)
     and Class C shares (Class C Plan), pursuant to Rule 12b-1 under the
     Investment Company Act of 1940 and a service plan for Class A shares (Class
     A Plan) (collectively, the Plans). The Class B and Class C Plans require
     the Fund to pay EVD amounts equal to 1/365 of 0.75% (annualized) of the
     Fund's average daily net assets attributable to Class B and Class C shares,
     for providing ongoing distribution services and facilities to the Fund. The
     Fund will automatically discontinue payments to EVD during any period in
     which there are no outstanding Uncovered Distribution Charges, which are
     equivalent to the sum of (i) 6.25% of the aggregate amount received by the
     Fund for the Class B and Class C shares sold, plus (ii) interest calculated
     by applying the rate of 1% over the prevailing prime rate to the
     outstanding balance of Uncovered Distribution Charges of EVD, of each
     respective class, reduced by the aggregate amount of contingent deferred
     sales charges (see Note 6) and daily amounts theretofore paid to EVD by
     each respective class. The Fund paid or accrued $119,385 and $245,439 for
     Class B and Class C shares, respectively, to or payable to EVD for the
     period from the start of business, May 30, 2003, to April 30, 2004,
     representing 0.75% (annualized) of the average daily net assets for Class B
     and Class C shares, respectively. At April 30, 2004, the amount of
     Uncovered Distribution Charges of EVD calculated under the Plans was
     approximately $1,863,000 and $4,650,000 for Class B and Class C shares,
     respectively.

     The Plans authorize the Fund to make payments of service fees to EVD,
     investment dealers and other persons in amounts equal to 0.25% (annualized)
     of the Fund's average daily net assets attributable to Class A, Class B and
     Class C shares for each fiscal year. Service fee payments are made for
     personal services and/or the maintenance of shareholder accounts. Service
     fees are separate and distinct from the sales commissions and distribution
     fees payable by the Fund to EVD and, as such, are not subject to automatic
     discontinuance when there are no outstanding Uncovered Distribution Charges
     of EVD. Service fees paid or accrued for the period from the start of
     business, May 30, 2003, to April 30, 2004 amounted to $106,099, $39,802,
     and $82,888 for Class A, Class B and Class C shares, respectively.

6    CONTINGENT DEFERRED SALES CHARGE

     A contingent deferred sales charge (CDSC) generally is imposed on
     redemptions of Class B shares made within six years of purchase and on
     redemptions of Class C shares made within one year of purchase. Generally,
     the CDSC is based upon the lower of the net asset value at date of
     redemption or date of purchase. No charge is levied on shares acquired by
     reinvestment of dividends or capital gain distributions. Class A shares may
     be subject to a 1% CDSC if redeemed within one year of purchase (depending
     upon the circumstances of purchase). The Class B CDSC is imposed at
     declining rates that begin at 5% in the case of redemptions in the first
     and second year after purchase, declining one percentage point each
     subsequent year. Class C shares will be subject to a 1% CDSC if redeemed
     within one year of purchase.

     No CDSC is levied on shares which have been sold to EVM or its affiliates
     or to their respective employees or clients and may be waived under certain
     other limited conditions. CDSC pertaining to Class B and Class C
     redemptions are paid to EVD to reduce the amount of Uncovered Distribution
     Charges calculated under the Class B and Class C Plans, respectively (see
     Note 5). CDSC assessed on Class B and Class C shares when no Uncovered
     Distribution Charges exist for the respective classes will be credited to
     the Fund. EVD received approximately $38,000 and $8,000 of CDSC paid by
     shareholders for Class B shares and Class C shares, respectively, for the
     period from the start of business, May 30, 2003, to April 30, 2004. EVD did
     not receive any CDSC from shareholders for Class A shares for the period
     from the start of business, May 30, 2003, to April 30, 2004.

7    INVESTMENTS TRANSACTIONS

     Purchases and sales of investments, other than short-term obligations,
     aggregated $333,807,306 and $110,022,492 respectively, for the period from
     the start of business, May 30, 2003, to April 30, 2004.

8    FEDERAL INCOME TAX BASIS OF UNREALIZED APPRECIATION (DEPRECIATION)

     The cost and unrealized appreciation (depreciation) of investments of the
     Fund at April 30, 2004, as computed on a federal income tax basis, were as
     follows:

9    FINANCIAL INSTRUMENTS

     The Fund may trade in financial instruments with off-balance sheet risk in
     the normal course of its investing activities to assist in managing
     exposure to various market risks. These financial instruments include
     written options, forward foreign currency exchange contracts, and financial
     futures contracts and may involve, to a varying degree, elements of risk in
     excess of the amounts recognized for financial statement purposes.

     The notional or contractual amounts of these instruments represent the
     investment the Fund has in particular classes of financial instruments and
     does not necessarily represent the amounts potentially subject to risk. The
     measurement of the risks associated with these instruments is meaningful
     only when all related and offsetting transactions are considered. The Fund
     did not have any open obligations under these financial instruments at
     April 30, 2004.

10   LINE OF CREDIT

     The Fund participates with other portfolios and funds managed by EVM and
     its affiliates in a $150 million unsecured line of credit agreement with a
     group of banks. Borrowings will be made by the Fund solely to facilitate
     the handling of unusual and/or unanticipated short term cash requirements.
     Interest is charged to each participating portfolio or fund based on its
     borrowings at an amount above either the Eurodollar rate or Federal Funds
     rate. In addition, a fee computed at an annual rate of 0.10% on the daily
     unused portion of the line of credit is allocated among the participating
     portfolios and funds at the end of each quarter. The Fund did not have any
     significant borrowings or allocated fees during period from the start of
     business, May 30, 2003, to April 30, 2004.

TO THE TRUSTEES OF EATON VANCE MUTUAL FUNDS TRUST AND SHAREHOLDERS OF EATON
VANCE TAX-MANAGED DIVIDEND INCOME FUND:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of Eaton Vance Tax-Managed Dividend Income Fund
(the Fund), as of April 30, 2004, and the related statement of operations, the
statement of changes in net assets, and the financial highlights for the period

statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audit.

We conducted our audit in accordance with standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities held as of April 30, 2004 by correspondence with the custodian and
brokers; where replies were not received from brokers, we performed other
auditing procedures. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
Eaton Vance Tax-Managed Dividend Income Fund at April 30, 2004, the results of
its operations, the changes in its net assets and the financial highlights for

     rendered by the principal accountant relating to tax compliance, tax
     advice, and tax planning and specifically include fees for tax return
     preparation.

(3)  All other fees consist of the aggregate fees billed for products and
     services provided by the principal accountant other than audit,
     audit-related, and tax services.

*  The Fund commenced operations on May 30, 2003. The Fund is the only Series
   with an April 30 fiscal year end.

(e)(1) The registrant's audit committee has adopted policies and procedures
relating to the pre-approval of services provided by the registrant's principal
accountant (the "Pre-Approval Policies"). The Pre-Approval Policies establish a
framework intended to assist the audit committee in the proper discharge of its
pre-approval responsibilities. As a general matter, the Pre-Approval Policies
(i) specify certain types of audit, audit-related, tax, and other services
determined to be pre-approved by the audit committee; and (ii) delineate
specific procedures governing the mechanics of the pre-approval process,
including the approval and monitoring of audit and non-audit service fees.
Unless a service is specifically pre-approved under the Pre-Approval Policies,
it must be separately pre-approved by the audit committee.

The Pre-Approval Policies and the types of audit and non-audit services
pre-approved therein must be reviewed and ratified by the registrant's audit
committee at least annually. The registrant's audit committee maintains full
responsibility for the appointment, compensation, and oversight of the work of
the registrant's principal accountant.

(e)(2) No services described in paragraphs (b)-(d) above were approved by the
registrant's audit committee pursuant to the "de minimis exception" set forth in
Rule 2-01(c)(7)(i)(C) of Regulation S-X.

billed for services rendered to the Eaton Vance organization by PWC and D&T for

investment adviser and any entity controlling, controlled by, or under common
control with the adviser that provides ongoing services to the registrant that
were not pre-approved pursuant to Rule 2-01(c)(7)(ii) of Regulation S-X is
compatible with maintaining the principal accountants' independence.
